Locks of Love is tangled in scandal. According to a new report from watchdog group Nonprofit Investor (NPI), the West Palm Beach-based charity–which collects human hair to make custom-fitted hair prosthesis for children suffering from medical hair loss–can’t account for $6 million worth of follicle donations.

Here’s how it breaks down. Every year, says NPI, LoL gets enough hair to make 2,080 wigs. That number is based on estimates LoL representatives shared with mediaoutlets in the past about how it gets 104,000 donations a year, roughly 20% of which are suitable for repurposing, due to issues with length and coloring.

Yet, in 2011, Locks of Love made just 317 of its natural hairpieces. That leaves 1,763 hairpieces unaccounted for, which NPI values at $6.6 million, based on manufacturing costs and retail value of other natural hair wigs.

When NPI showed LoL those findings earlier this year, the charity stated that it “does not count, catalogue nor maintain lists of hair donations,” as NPI founded Kent Chao explained on Forbes.com. In response to the published report, LoL President Madonna Coffman told ABC News: “I don’t know what the purpose would be to count hair donations. We made 317 that year because we had 317 requests. Some of the donated hair is sold to finance the making of its custom wigs. The unused hair stays in inventory until a request comes in.”
